Senior Platform Software Engineer - Platform Architect

About This Role

This platform architect role focuses on extending the BMC from a traditional server management controller into a secure management authority for both system management and Ethernet switch management, while preserving clear separation between the BMC management plane and the switch data plane. The engineer will help define and implement OpenBMC-based management for systems that include host CPUs, BMCs, and coordinated top-of-rack Ethernet switching functionality, contributing to the next generation of OpenBMC networking architecture.

Responsibilities

• Architect and implement OpenBMC support for platforms where the BMC handles host system functions and a coordinated ToR Ethernet switch subsystem
• Define the end-to-end switch-management architecture across OpenBMC D-Bus services, bmcweb/Redfish APIs, persistent configuration, eventing, telemetry, security, and backend switch control interfaces
• Develop OpenBMC object models and services for switch inventory, switch ASICs, front-panel ports, internal ports, PHYs, optics, retimers, VLANs, LAGs, FDB entries, counters, sensors, and health state
• Implement L2 networking capabilities including port admin control, speed and FEC configuration, auto-negotiation, breakout, VLAN creation and membership, access/trunk mode, MAC learning, FDB management, flooding controls, link aggregation, and loop-prevention features
• Build backend abstraction layers that can integrate with Linux switchdev/netlink, SAI/SONiC/SWSS-style components, DENT-style Linux networking components, or vendor switch ASIC SDKs
• Work closely with hardware, ASIC, security, firmware, QA, manufacturing, and cloud infrastructure networking teams to influence board architecture, schematics, manageability interfaces, and production test strategy
• Write and review design specifications, API documentation, code, unit tests, hardware-in-loop tests, integration tests, and QA plans required to productize the architecture

Requirements

• Bachelor's degree or higher, or equivalent experience, in Computer Science, Electrical and Electronics Engineering, or a related field with 12+ years of relevant experience
• Strong OpenBMC firmware development experience on x86 or ARM-based server environments, such as Yocto, systemd, D-Bus, phosphor services, bmcweb, Redfish, firmware update, device monitoring, and platform security
• Hands-on experience with Ethernet switch architecture and L2 features such as VLANs, trunks, access ports, LAG/LACP, STP/RSTP, LLDP, FDB/MAC learning, storm control, ACLs, QoS, PHY management, and transceiver diagnostics
• System management software experience with rack or blade server platforms, including IPMI, KCS, Redfish, PLDM, MCTP, SPDM, secure firmware update, attestation, and BMC-host communication
• Strong programming and debugging skills in C/C++ and Python, with familiarity in Bash, Go, or Rust; ability to develop reliable Linux user-space services and review low-level system code
